We call them SOLDER FERRULES in the shipyard industry. Been using them for about 12 years myself. They've been there even longer.

[johnstewart]

I was using these in the 70's, these were used by the military as wire repairs on aircraft. I like it when people discover new/old stuff.
Raychem was the company, we had an entire kit with an air gun to activate the splice. We couldn't have exposed elements as the fuel vapors were always a factor

[metalguru]

Did you say 'NEW'? I was using these 25 years ago.😂😂

[gmaurice]

We called them Solder Sleeves always my go to. I've been using them for about 15 years.

[Greg]

That's really cool, now I *wish* I had something that needed to be soldered.

I've been using these a lot lately; and, to make them even better, I use standard thickness heat-shrink tubing over top of them once they're secured - this gives them a bit more rigidity, and also considerably more protection, as the heating required to melt the solder of these does thin the tubing quite a bit.

[derekjenkinson]

New type 😂😂😂😂, I was using these during my apprenticeship. I started in 1989!

[nicholasclay]

Dip the wires in flux before you join them, the results will be dramatic and I don’t think you’ll be able to rip them apart.

[patrickcallahan]

I've had good luck with these the last few years. I have found that the tighter you can get the strands for the joint the better the solder will work. My best results have been with doing twisting them together before heating as that leads to less airspace in the joint and as the solder heats up at the last moment the compression from the contracting shrink tube will push the solder more fully into the joint. Also if you have any stray strands poking towards the shrink tube as that tube shrinks it can impale itself on the pointy strand and cause a failure.
I carry a small set of these in my emergency kit for the car as well as a small butane cigar lighter (for better heat control using short pulses) :)

I was literally using these when I got the notification 😆

Given their cost and the number of use cases for these things, I think I'd rather spend the extra effort just to solder and heatshrink them properly. True solder is way better than this stuff and with glued heats shrink tubing you're much more water proof than this and the joint is actually stronger than the original wire is. You also don't have to worry about a high heat day (like if this was in an engine compartment) reflowing your solder and causing problems. It looses all of it's mechanical strength at a relatively low temperature which is how a heat gun can even melt it in the first place, it's usually a low melting alloy like indium and gallium those fun metals that melt on a human body mixed with something else to raise it up a bit. No idea how that stuff behaves long term, lead in solder is pretty well tried and true and still mandated to be used in certain applications because of it's known properties.

I don’t know but soldering for me is satisfying especially if there is a bunch of wires and after you are done they all look perfect and yeah that might be the quickest and overall good but it’s also the most expensive

[iggy]

These can also be activated with a common pocket lighter if done carefully to control the amount of heat applied. That's EXACTLY how I fixed the wiring harness underneath my camper in a parking lot, about 200 miles from home. I lost brake and turn signal lights. A wire had been wedged between two parts of the frame, frayed and broke. A solder sleeve and a lighter came to the rescue!

[turbotalon]

Been using these for automotive installs for years, they really work great!

[bowhite]

I've used them for years and definitely my go to wire repair method. The smaller they are the easier and quicker they are to use. At first the larger ones can blow out the shrink wrap before melting or fully melting the solder but once you master using the right amount of heat and technique they are great to use.

"Speed and convenience of a crimp on connector"

Ha.

[techguy]

I was an aircraft electrician and this is fairly close to what we would use. The difference is that we would have a metal barrel that we would crimp onto each end of the wire, then slide the plastic tube over the barrel and heat shrink it. It was referred to as an environmental splice.

[thanatoslrsd]

I've had these for a while now and have used them on a few repairs. I found that the shrinking plastic is fairly thin after done, and I still use heat-shrink over these every time I use them. The heat-shrink also looks better than the look of the solder-seal IMHO. Keep up the great videos!

[johnwkomdat]

Thank you for introducing me to these. I had been putting off a rewiring job in my car because I couldn't figure out how to get my soldering setup into the cramped space (behind the glove box). These solved the problem, and my TPMS light is no longer stuck on!

[Wizardnil]

I LIVE by these now - Redid my entire lightbar setup with these and it looks great!
